What you get

  • The lazy senior developer ruleset: before writing code the agent climbs a decision ladder (is it needed, does something reusable exist, is there a built-in) and only then writes the minimum.
  • The repo reports 54% fewer lines and 20% lower cost on its benchmarks.
  • Injected at session start as a skill or AGENTS.md.

Install the Ponytail skill

Pick your agent. The wrapper only tells your agent how to start a session. The skill's instructions arrive with each session, after your access is checked.

  1. Sign in once from your terminal.

    Terminal
    skillgild login
  2. Install this skill for Claude Code.

    Terminal
    skillgild install ponytail --agent claude-code
  3. Register the SkillGild MCP server with Claude Code.

    Terminal
    claude mcp add --scope user skillgild -- $(command -v skillgild) mcp

How it runs

  1. Your agent starts a session. SkillGild checks your access and allowance, counts one run, and sends the skill's instructions for this task.
  2. Your agent does the work with its own model and tools, in your project. SkillGild makes no AI model call.

Use it from code

Start a session, follow its guide, then end it. Create an API key under Account and pass it as a bearer token.

Terminal
# Prints the session ID, its tools and the instructions for your agent
skillgild session ponytail
skillgild end <session-id>

Questions

How do I install Ponytail in Claude Code?

Run skillgild install ponytail --agent claude-code and connect the SkillGild MCP server (skillgild mcp). When a task matches, your agent starts a session, which uses one of your 25 free runs this month, and follows the skill's instructions. Use --agent codex, cursor or gemini-cli for other clients.

Is Ponytail free?

Yes. It includes 25 free runs every month on SkillGild. Ponytail is open source (MIT) by Dietrich Gebert; SkillGild packages it from https://github.com/DietrichGebert/ponytail at a pinned commit and credits the author.

Does Ponytail run on SkillGild?

It runs in your coding agent with your own model. SkillGild checks your monthly allowance and delivers the skill's instructions for each session; it makes no model call and never sees your project unless your agent sends it.

Which agents does Ponytail work with?

The project lists Claude Code, Codex, Cursor, Copilot, Windsurf, Cline, Kiro, OpenCode, Gemini and 10+ others. It is a plain Agent Skills folder (SKILL.md plus supporting files), so any client that reads that format can load it.
